I just spent a good deal of time explaining how to do the cuts you asked about only to have my session time out before I could post a reply which is a real ****** and a wee bit frustrating. I will try again later
china markers do work very well but they are fragile and the paper wrapper does not hold up very well if you have wet hands or if left on workbench near wetsaw,must handle with care
I make the radius cuts with a grinder or a wet saw.It depends upon how small or large the radius is and the diameter of the blade you are cutting with.I can give more details on how to make these cuts if you like.or I could e mail a short video showing you how. Stanimal
sorry for going off the beaten track here but i put granite down in 2 rooms in my house and spent a silly amount of time getting the tiles as close together as possible and even more time with that horrible "gloss black" grout stuff (if you can call it grout (disgusting stuff). made a hell of difference from black grout that eventually goes grey.
with an expensive tile like this its really worth the extra time. there you go i have said my bit!:hurray:
I have used black Silicon to fill joints on dark stone when using a butt joint and it has remained black. I usually grout with tile grout as per customer specs.
